RESUMO

BACKGROUND: Lower respiratory tract infections are the leading cause of mortality in young children globally. In many resource-limited settings clinicians rely on guidelines such as IMCI or ETAT + that promote empiric antibiotic utilization for management of acute respiratory illness (ARI). Numerous evaluations of both guidelines have shown an overall positive response however, several challenges have also been reported, including the potential for over-prescribing of unnecessary antibiotics. The aims of this study were to describe the antibiotic prescribing practices for children less than 24 months of age with symptoms of ARI, that were admitted to Kenema Government Hospital (KGH) in the Eastern Province of Sierra Leone, and to identify the number of children empirically prescribed antibiotics who were admitted to hospital with ARI, as well as their clinical signs, symptoms, and outcomes. METHODS: We conducted a prospective study of children < 24 months of age admitted to the KGH pediatric ward with respiratory symptoms between October 1, 2020 and May 31, 2022. Study nurses collected data on demographic information, medical and medication history, and information on clinical course while hospitalized. RESULTS: A total of 777 children were enrolled. Prior to arrival at the hospital, 224 children (28.8%) reported taking an antibiotic for this illness without improvement. Only 15 (1.9%) children received a chest radiograph to aid in diagnosis and 100% of patients were placed on antibiotics during their hospital stay. CONCLUSIONS: Despite the lives saved, reliance on clinical decision-support tools such as IMCI and ETAT + for pediatric ARI, is resulting in the likely over-prescribing of antibiotics. Greater uptake of implementation research is needed to develop strategies and tools designed to optimize antibiotic use for ARI in LMIC settings. Additionally, much greater priority needs to be given to ensuring clinicians have the basic tools for clinical diagnosis, as well as greater investments in essential laboratory and radiographic diagnostics that help LMIC clinicians move beyond the sole reliance on algorithm based clinical decision making.

RESUMO

This paper explores individual, interpersonal- and household-level factors influencing HIV-related sexual risk behaviour among adolescent girls who participated in an intervention to reduce HIV risk in a rural setting in Mozambique. Twenty-eight adolescent girls ages 13-19, 30 heads of household, and 53 influential men participated in in-depth interviews at two time points. Comparative analysis compared girls who reported reducing risk behaviours over time to girls who did not and identified factors that respondents described as influential to behaviour change. Among the twenty girls self-reporting sexual risk at the first time point, half had reduced these behaviours one year later. Changes in girls' behaviours were contingent upon household- and interpersonal-level factors, particularly households' economic stability and family members' financial support. Future interventions with adolescents in similar settings should evaluate and leverage household and family support to achieve sexual risk reduction.

RESUMO

Women First was a combined economic and social empowerment intervention implemented between 2010 and 2015 in Zambézia Province, Mozambique. The intervention was designed to reduce adolescent girls' risk of HIV and gender-based violence, improve school attendance and empower girls. However, perceptions of girls' improved respectfulness also emerged as an unanticipated effect during the programme evaluation. In this paper, we explore emic definitions of respect and girls' good behaviour and perceptions of how the intervention caused improvements in behaviour from the perspective of intervention participants, their heads of household, influential men in their lives, and community members. In depth interviews and focus group discussions were conducted at two time points in 12 rural communities where the intervention was implemented. Respondents described "good girls" as deferential and obedient; productive and willing to serve their families and communities; and sexually chaste and modestly dressed. Respondents believed the intervention had reinforced or taught these behaviours, although they were generally aligned with gender norms that were not part of the formal intervention content and sometimes contrary to the intervention's primary goals. Implications for future sexual and reproductive health programmes are discussed.

RESUMO

BACKGROUND: Concerns have been expressed in relation to a possible negative effect of fentanyl epidural analgesia on breastfeeding rates. A 2016 systematic review was inconclusive and suggested cohort studies be performed with control groups to allow for other potential confounding factors. AIMS: To assess the effect of fentanyl epidural analgesia in labour on breastfeeding practices. MATERIAL AND METHODS: A prospective cohort study, conducted at a metropolitan hospital, Ipswich, Queensland. Eligible women were first-time mothers, wishing to breastfeed after a vaginal birth at term. Women who had fentanyl epidural only (107) were compared with women who had subcutaneous morphine only (90), and women who had neither subcutaneous morphine nor epidural (107). RESULTS: Fewer women in the fentanyl epidural analgesia group were fully breastfeeding when leaving hospital (54.2% compared to 69.2% in the no analgesia group and 77.8% in the subcutaneous morphine group; P < 0.05). At 6 weeks postpartum, there was no evidence of difference between the groups (43% for fentanyl epidural analgesia, 52.3% for no analgesia group and 48.9% for subcutaneous morphine group; P = 0.63). Rates of induction of labour, instrumental birth and admission to special care nursery differed significantly between groups and when controlled for these, there was no association between fentanyl epidural analgesia and breastfeeding at discharge (adjusted odds ratio (OR) 0.74; 95% CI 0.39-1.41) or at 6 weeks postpartum (OR 0.75; 95% CI 0.41-1.38). CONCLUSION: Our study did not find an association between fentanyl epidural analgesia in labour and rates of fully breastfeeding at discharge and at 6 weeks postpartum.

RESUMO

OBJECTIVES: The purpose of this study was to document the baseline neurophysiological status (skin conductance activity levels) of patients presenting for physiotherapy with acute and subacute low back pain (symptoms of up to 12 weeks' duration) and to observe the magnitude and direction of sympathetic nervous system (SNS) changes (skin conductance responses [SCRs]) occurring as a result of receiving guideline-endorsed physiotherapy treatment. METHODS: A pragmatic, prospective, longitudinal, observational study recording SNS skin conductance (SC) responses and patient reported outcome measure changes to a program of guideline-endorsed physiotherapy treatment for low back pain symptoms of up to 12 weeks' duration. Sixty patients received a guideline-endorsed physiotherapy treatment program. Continuous neurophysiological recordings of SC activity levels were taken throughout each treatment. Patient reported outcome measure data were extracted from inception, midpoint, and discharge. Within and between treatment analyses determined the nature of SC changes and correlations to longitudinal changes in pain and function. Skin conductance changes were measured within and between treatment episodes at treatment inception, midpoint, and discharge and observed correlations between the magnitude of SCRs, pain abatement (numeric pain rating scale), and functional restoration (Oswestry Disability Index). RESULTS: Skin conductance changes were significant during all "treatment" periods (P = .044), with the greatest magnitude of sympathoexcitatory responses occurring at inception (219%). The treatment modality providing the maximum SNS response was a high-velocity lumbar rotation manipulation. Positive correlations were identified between SCRs, Oswestry Disability Index improvements (r = 0.82, P < .0005), and pain abatement (r = 0.459, P < .0005). CONCLUSIONS: Patients with low back pain exhibited neurophysiological treatment responses indicative of a symptom-related neuroplastic state of dorsal horn sensitization that may be receptive to early manual therapy intervention.

RESUMO

BACKGROUND: Malaria is the leading cause of death among children in Mozambique. Prevalence and factors associated with malaria are not well studied among children in rural Zambézia Province. Whether prevalence of malaria varies across diverse districts within the province is unknown. METHODS: A cross-sectional survey of female heads of household was conducted during April and May 2014, a period of peak malaria transmission. Data were collected on up to two randomly selected children aged 6-59 months per household. The outcome of interest was self-report of symptomatic malaria confirmed by diagnostic test in the past 30 days. Analyses accounted for the two-stage cluster sample design. Prevalence of symptomatic malaria was calculated for the province and three over-sampled focus districts-Alto Molócuè, Morrumbala, and Namacurra. Multivariable logistic regression of symptomatic malaria diagnosis included: district, age, sex, education, bed net use, urban setting, distance to health facility, income, roofing material, and pig farming. RESULTS: Data were collected on 2540 children. Fifty percent were female, and the median age was 24 months. Sixty percent of children slept under bed nets the night prior to the survey, but utilization varied between districts (range 49-89%; p < 0.001). Forty-three percent of children reported fever in the past 30 days, 91% of those sought care at a health facility, 67% of those had either a malaria rapid diagnostic test or blood smear, and 67% of those had a positive test result and therefore met our case definition of self-reported symptomatic malaria. There were significant differences in prevalence of fever (p < 0.001), health-seeking (p < 0.001), and diagnostic testing (p = 0.003) between focus districts. Province-wide prevalence of symptomatic malaria was 13% and among focus districts ranged from 14% in Morrumbala to 17% in Namacurra (p < 0.001). Higher female caregiver education (OR 1.88; 95% CI 1.31-2.70), having fewer young children in the household (OR 1.25; 95% CI 1.01-1.56), and higher income (OR 1.56; 95% CI 1.11-2.22) were independently associated with having a child with symptomatic malaria. CONCLUSIONS: Self-reported symptomatic malaria is highly prevalent among children in Zambézia Province, Mozambique and varies significantly between diverse districts. Factors facilitating access to health services are associated with symptomatic malaria diagnosis. These findings should inform resource allocation in the fight against malaria in Mozambique.

RESUMO

Intra-vaginal drying and tightening and labia minora elongation are commonly practised in some parts of southern Africa. We sought to capture data on these practices among women living in Zambézia province, Mozambique. Information was gathered from 3543 female heads of household on > 500 variables, including vaginal practices, in 2014. Women who planned to use intra-vaginal tightening substances had 1.84 times higher odds of ever receiving an HIV test (p < 0.001) and 1.40 times higher odds of at least one antenatal care visit attended during last pregnancy (p = 0.015). Women who had or planned to undergo labia minora elongation had 2.61 times higher odds of receiving an HIV test in the past (p < 0.001) and 1.60 times higher odds of attending at least one antenatal care visit during their last pregnancy (p < 0.001). There was little evidence for a relationship between self-reported HIV status and anticipated use of intra-vaginal tightening substances (p = 0.21). Current or anticipated participation in labia elongation showed a protective effect on HIV infection (p = 0.028). Given documented associations between intra-vaginal substance use, vaginal infections and HIV acquisition, understanding the prevalence of vaginal practices is an essential component to addressing the epidemic.

RESUMO

BACKGROUND: Malaria remains a major threat to some 3.2 billion persons globally. Malaria contributes heavily to the overall disease burden in Mozambique and is considered endemic. A cornerstone of Mozambique's vector control strategy has been to strive for universal coverage of insecticide-treated nets (ITN). METHODS: The study is a population-based cross-sectional survey of female heads-of-household in Zambézia Province, Mozambique conducted during August-September, 2010 and April-May, 2014. Analyses accounted for a stratified two-stage cluster sample design. Outcomes of interest included sleeping under a mosquito net during the previous night. Descriptive statistics were calculated for three oversampled districts and for the entire province. Multivariable logistic regression analysis was used to estimate factors associated with both changes over time and increased mosquito bed net usage. RESULTS: Of the 3916 households interviewed in 2010 and 3906 households in 2014, 64.3% were in possession of at least one mosquito bed net. A higher proportion of households in Namacurra (90%) reported possession of a mosquito net, compared to Alto Molócuè (77%) and Morrumbala (34%), respectively in 2014. Of pregnant respondents, 58.6% reported sleeping under a mosquito net the previous night in 2010 compared to 68.4% in 2014. Fifty percent of children 0-59 months slept under a mosquito net the previous night in 2010 compared to 60% in 2014. Factors associated with use of a mosquito net for female head-of-household respondents were higher education, understanding Portuguese, larger household size, having electricity in the household, and larger household monthly income. As travel time to a health facility increased (per 1 h), respondents had 13% lower odds of sleeping under a mosquito net (OR 0.87; 95% CI 0.74-1.01, p = 0.07). Pregnant women in 2014 had a 2.4 times higher odds of sleeping under a bed net if they lived in Namacurra compared to Alto Molócuè (95% CI 0.91-6.32, p = 0.002 for district). Higher maternal education, living in Namacurra, and acquisition of mosquito bed nets were associated with a child 0-59 months reporting sleeping under the net in the previous night in 2014. CONCLUSIONS: Intensified focus on the poorest, least educated, and most distant from health services is needed to improve equity of ITN availability and usage. Additionally, while some districts have already surpassed goals in terms of coverage and utilization of ITN, renewed emphasis should be placed on bringing all geographic regions of the province closer to meeting these targets.

RESUMO

BACKGROUND: Fetomaternal alloimmune thrombocytopenia (FMAIT) is caused by human platelet (PLT) antigen (HPA) incompatibility. Beads coupled with recombinant ß3 integrins, displaying the biallelic HPA-1 epitopes (rHPA-1), have been shown to detect HPA-1a alloantibodies implicated in FMAIT. This report describes a multicenter validation of the beads using the results of well-characterized samples to define the optimum parameters for analysis of a large cohort of 498 clinical samples. STUDY DESIGN AND METHODS: Fifty-one blinded quality assurance (QA) samples were tested by six laboratories to standardize the rHPA-1 bead assay and to develop an algorithm for sample classification. Five laboratories retrieved samples from 498 independent FMAIT cases, previously tested by the monoclonal antibody-specific immobilization of PLT antigens (MAIPA) assay, from their local archives for testing with the rHPA-1 beads. The results were evaluated using a mathematical algorithm developed to classify the samples. RESULTS: The QA samples gave a mean concordance of 94% between the bead and MAIPA assays, while 97% concordance was observed with the FMAIT samples. Of the 15 discrepant samples, seven were positive by the beads but negative by MAIPA, while the contrary was observed for eight samples. Overall, the bead assay achieved 98% sensitivity for HPA-1a antibody detection in FMAIT and 98.7% specificity compared to the local MAIPA. CONCLUSION: The rHPA-1 bead assay is a rapid 3-hour assay for the sensitive detection of HPA-1 antibodies. Its ease of use would enable prompt detection of maternal HPA-1a antibodies in suspected FMAIT cases, which is important supportive evidence for treatment by transfusion with HPA-1b1b PLTs.

RESUMO

Every year, ovarian cancer kills approximately 14,000 women in the United States and more than 140,000 women worldwide. Most of these deaths are caused by tumors of the serous histological type, which is rarely diagnosed before it has disseminated. By deep paired-end sequencing of mRNA from serous ovarian cancers, followed by deep sequencing of the corresponding genomic region, we identified a recurrent fusion transcript. The fusion transcript joins the 5' exons of ESRRA, encoding a ligand-independent member of the nuclear-hormone receptor superfamily, to the 3' exons of C11orf20, a conserved but uncharacterized gene located immediately upstream of ESRRA in the reference genome. To estimate the prevalence of the fusion, we tested 67 cases of serous ovarian cancer by RT-PCR and sequencing and confirmed its presence in 10 of these. Targeted resequencing of the corresponding genomic region from two fusion-positive tumor samples identified a nearly clonal chromosomal rearrangement positioning ESRRA upstream of C11orf20 in one tumor, and evidence of local copy number variation in the ESRRA locus in the second tumor. We hypothesize that the recurrent novel fusion transcript may play a role in pathogenesis of a substantial fraction of serous ovarian cancers and could provide a molecular marker for detection of the cancer. Gene fusions involving adjacent or nearby genes can readily escape detection but may play important roles in the development and progression of cancer.

RESUMO

INTRODUCTION: Patient satisfaction with clinical services can have an effect on retention in HIV care and adherence to antiretroviral therapy. This study assessed patient satisfaction and its association with retention and viral suppression in Zambézia Province, Mozambique. METHODS: Monthly exit interviews with persons living with HIV were completed from August 2017-January 2019 in 20 health facilities; clinical data were extracted from medical records. Regression analyses assessed the effect of satisfaction scores on retention and viral suppression, adjusting for age, sex, education, civil status, time on treatment, and site. Satisfaction scores were correlated with time spent at health facilities using generalized linear regression models. RESULTS: Data from 4388 patients were analyzed. Overall median satisfaction score was 75% (IQR 53%-84%); median time spent at facilities (from arrival until completion of clinical services) was 2h54min (IQR 1h48min-4h). Overall satisfaction score was not associated with higher odds of retention or viral suppression, but association was seen between satisfaction regarding attention given to patient and respect and higher odds of viral suppression. Patient satisfaction was negatively associated with time spent in facility (Spearman's correlation -0.63). Increased time spent at facility (from 1 to 3 hours) was not associated with lower retention in care (OR 0.72 [95%CI:0.52-1.01] and 0.83 [95%CI: 0.63-1.09] at 6- and 12-months, respectively), nor with a lower odds of viral suppression (OR 0.96 [95%CI: 0.71-1.32]). CONCLUSIONS: Strategies to reduce patient wait times at the health facility warrant continued prioritization. Differentiated models of care have helped considerably, but novel approaches are still needed to further decongest crowded health facilities. In addition, a good client-provider communication and positive attitude can improve patient satisfaction with health services, with an overall improved retention.

RESUMO

BACKGROUND: Most recently described human platelet antigens (HPAs) have been detected in cases of fetomaternal alloimmune thrombocytopenia (FMAIT) where the mother has been immunized against a low-frequency antigen that the fetus has inherited from the father. Low-frequency antigens are not represented in normal panel platelets (PLTs) and antibody detection and identification in such cases requires incubation of maternal serum with paternal PLTs and definition of the causative mutation. STUDY DESIGN AND METHODS: A suspected case of FMAIT was investigated for PLT-specific antibodies using a panel of both HPA-typed and paternal PLTs. HPA typing was performed by polymerase chain reaction with sequence-specific primers and further DNA analysis was performed using direct sequencing of the coding regions of the ITGA2B and ITGB3 genes. RESULTS: Maternal antibodies reactive only with paternal PLTs were localized to glycoprotein (GP)IIb/IIIa using the monoclonal antibody immobilization of PLT antibody assay. A single-nucleotide polymorphism was detected in Exon 23 of ITGA2B in the father and affected child, which predicted a V740L substitution in the mature protein. Recombinant V740L mutated GPIIb expressed in HEK293 cells was specifically recognized by maternal antibodies. The polymorphism was not detected either in the mother or in a cohort of 100 donors. CONCLUSION: The V740L polymorphism defines a new low-frequency antigen implicated in two cases of FMAIT in a single family. Low-frequency HPAs are clinically important and their elucidation requires both crossmatch studies and gene sequencing in cases where there is strong clinical evidence of FMAIT but initial laboratory investigations do not support the diagnosis.

RESUMO

OBJECTIVE/AIM: To evaluate the safety of transfusing pooled, whole blood-derived granulocytes in additive solution and plasma (GASP) in 30 recipients. BACKGROUND: Demand for granulocytes in England has increased five-fold. With the advantages of reduced red cell, plasma and overall volume, GASP maintains function in vitro. METHODS AND MATERIALS: Observations were recorded prior to and post transfusion. Increments were recorded at 1 h and the following morning. Leucocyte antibody screening was undertaken prior to and at 1-6 months following transfusion. RESULTS: Thirty patients aged between 8 months and 68 years received 221 GASP in 148 transfusion episodes. GASP contained an average of 1.0 × 10(10) granulocytes in 207 mL. Adults usually received two packs and children 10-20 mL kg(-1). Children and adults received a median [interquartile range (IQR)] dose of 12.5 (9.1-25.3) and 19.7 (12.0-25.8) × 10(9) granulocytes per transfusion, respectively. There was one episode of transfusion-associated circulatory overload (TACO) in a patient with chronic cardiac failure following 600 mL of unpooled granulocytes, other fluids and one GASP. New leucocyte alloimmunisation occurred in 3/30 recipients 10%. No other significant reactions were reported. Median peripheral blood neutrophil increments at 1 h post transfusion were 0.06 (IQR, 0.01-0.17) in children and (0.03) (IQR, 0-0.16) in adults. CONCLUSION: GASP has a similar safety profile to other sources of granulocytes for patients with refractory infection or in need of secondary prophylactic transfusion. Further studies are required to clarify the role of GASP in the treatment of neutropenic patients.

RESUMO

BACKGROUND: Patients with human platelet antigen (HPA) specific antibodies in cases of neonatal alloimmune thrombocytopenia and platelet (PLT) refractoriness derive clinical benefit from the use of HPA-selected PLTs. STUDY DESIGN AND METHODS: This study describes three patients with underlying diagnoses of acute myeloid leukemia, chronic lymphocytic leukemia, and myelodysplasia, respectively, who underwent allogeneic bone marrow transplantation (BMT) with unrelated donors matched at the HLA-A, B, C, Dr, and DQ loci but who failed to achieve an adequate PLT count. Investigation using PLT immunofluorescence test, monoclonal antibody immobilization of PLT antigens assay, and genotyping revealed the presence of recipient-derived HPA-1a antibodies. RESULTS: In two patients, anti-HPA-1a was detected post-BMT and in the third patient, anti-HPA-1a was detected during pre-BMT chemotherapy. Despite apparent 100% engraftment of donor cells, the patients' PLT counts failed to recover 9-10 months posttransplant. The patients remained PLT-transfusion dependent and failed to achieve satisfactory increments following random donor or HLA-matched PLT transfusions. After the identification of HPA-1a antibodies, the patients were supported by HPA-1a(-) PLTs and satisfactory posttransfusion PLT increments were obtained. These cases illustrate that HPA-1a antibodies may remain detectable for 10 months following apparently successful donor engraftment and the disappearance of recipient-derived HLA antibodies. The prolonged persistence of recipient-derived PLT-specific antibodies following BMT has to our knowledge not been described previously. CONCLUSION: HPA-1a antibodies were associated with protracted PLT-transfusion dependence and significant hemorrhagic complications. Appropriate and timely laboratory investigation for HPA-specific antibodies followed by transfusion support with HPA-selected PLTs provided the cornerstone of the hemostatic management in these cases.

RESUMO

Anemia is an increasingly recognized problem in sub-Saharan Africa. To determine the magnitude, severity, and associated factors of anemia among hospitalized children aged 6-59 months, HIV-infected and HIV-exposed uninfected children (a child born to a known HIV-infected mother) with a documented fever or history of fever within the prior 24 hours of hospital admission (N = 413) were included in this analysis. Of 413 children enrolled, 364 (88%) were anemic, with 53% classified as mild anemia (hemoglobin [Hb] 7-9.9 g/dL). The most common diagnoses associated with hospital admission included acute respiratory illness (51%), malnutrition (47%), gastroenteritis/diarrhea (25%), malaria (17%), and bacteremia (13%). A diagnosis of malaria was associated with a decrease in Hb by 1.54 g/dL (P < 0.001). In HIV-infected patients, malaria was associated with a similar decrease in Hb (1.47 g/dL), whereas a dual diagnosis of bacteremia and malaria was associated with a decrease in Hb of 4.12 g/dL (P < 0.001). No difference was seen in Hb for patients on antiretroviral therapy versus those who were not. A diagnosis of bacteremia had a roughly 4-fold increased relative odds of death during hospitalization (adjusted odds ratio = 3.97; 95% CI: 1.61, 9.78; P = 0.003). The etiology of anemia in high-burden malaria, HIV, tuberculosis, and poor nutrition countries is multifactorial, and multiple etiologies may be contributing to one's anemia at any given time. Algorithms used by physician and nonphysician clinicians in Mozambique should incorporate integrated and non-disease specific approaches to pediatric anemia management and should include improved access to blood culture.

RESUMO

Support of human immunodeficiency virus (HIV) and tuberculosis (TB) testing and treatment supported by President's Emergency Plan for AIDS Relief (PEPFAR) in Africa requires immense quantities of tests and medications. We sought to use central pharmacy supply data of Mozambique's rural Zambézia Province (2017 population ≈5.11 million persons; ≈12.6% adult HIV prevalence in 2016) to examine shortages, stockouts, and trends in availability. Using stock surveillance for 60 weeks in 2014-2015, we assessed availability of 36 medications [4 classes: adult antiretroviral (ARV) medications, pediatric ARVs, anti-TB medications, and antibiotics] and diagnostic test kits (2 rapid tests for HIV; 1 each for malaria and syphilis). We contrasted these to 2018-2019 data. We modeled pharmacy data using ordinal logistic regression, characterizing weekly product availability in four categories: good, adequate, shortage, or complete stockout. We found 166 (7.7%) stockouts and 150 (6.9%) shortages among 2,160 weekly records. Earlier calendar time was associated with reduced medication supplies (p < .001). Certain medication/test kit classes were associated with reduced supply (p < .001). We found an interaction between time and medication class on the odds of reduced supply (p < .001). Pediatric ARVs had a 17.4 (95% confidence interval: 8.8-34.4) times higher odds of reduced medication supply compared with adult ARVs at study midpoint. Trends comparing the first and last weeks showed adult ARVs having 67% and pediatric having 71% lower odds of reduced supplies. Only adult ARV shortages improved amid growing demand. Data from 2018 to 2019 suggest continuing inventory management challenges. Monitoring of drug (especially pediatric) and test kit shortages is vital to ensure quality improvement to guarantee adequate supplies to enable patients and care providers to achieve sustained viral suppression. A central Mozambican drug repository in the nation's second largest Province continues to experience drug and rapid test kit stockouts.

RESUMO

Before the 2015 implementation of "Test and Start," the initiation of combination antiretroviral therapy (ART) was guided by specific CD4 cell count thresholds. As scale-up efforts progress, the prevalence of advanced HIV disease at ART initiation is expected to decline. We analyzed the temporal trends in the median CD4 cell counts among adults initiating ART and described factors associated with initiating ART with severe immunodeficiency in Zambézia Province, Mozambique. We included all HIV-positive, treatment-naive adults (age ≥ 15 years) who initiated ART at a Friends in Global Health (FGH)-supported health facility between September 2012 and September 2017. Quantile regression and multivariable logistic regression models were applied to ascertain the median change in CD4 cell count and odds of initiating ART with severe immunodeficiency, respectively. A total of 68,332 patients were included in the analyses. The median change in CD4 cell count under "Test and Start" was higher at +68 cells/mm3 (95% CI: 57.5-78.4) compared with older policies. Younger age and female sex (particularly those pregnant/lactating) were associated with higher median CD4 cell counts at ART initiation. Male sex, advanced age, WHO Stage 4 disease, and referrals to the health facility through inpatient provider-initiated testing and counseling (PITC) were associated with higher odds of initiating ART with severe immunodeficiency. Although there were reassuring trends in increasing median CD4 cell counts with ART initiation, ongoing efforts are needed that target universal HIV testing to ensure the early initiation of ART in men and older patients.

RESUMO

PURPOSE: An intervention including business training and health education was implemented in Mozambique, where girls are at elevated risk for acquiring HIV. As part of a mixed-methods evaluation, we describe perceived effects of the intervention on girls' sexual behavior and school attendance. METHODS: We conducted 49 in-depth interviews (IDIs) with girl intervention participants (ages 13-19), 24 IDIs with heads of girls' households, 36 IDIs with influential males identified by girls, and 12 focus group discussions with community members after the intervention ended and one year later. RESULTS: Informants said the primary intervention benefit was realized when girls had money to stay in or return to school and/or to buy necessities for themselves and their households-reducing their need for transactional or intergenerational sex. However, some girls did not make a profit and some businesses were not sustainable. Sometimes the intervention appeared to be implemented in a way to reinforce inequitable gender norms resulting in some girls feeling shame when they reengaged in risky sex after their businesses failed. CONCLUSIONS: Earning money enabled girls to potentially reduce their vulnerability to HIV. We offer recommendations for future multi-sector interventions, including the need to address potential harms in programs serving vulnerable girls.

RESUMO

BACKGROUND: The first pillar of the UNAIDS 90-90-90 goal seeks to accurately identify persons living with HIV (PLHIV), a process that is predicated on facilities having the necessary HIV tests available to perform the task. In many rural settings, the identification of PLHIV is accomplished through a two-step process involving the sequential use of 2 separate rapid diagnostic tests (RDTs). Inadequate inventory of either test has ramifications for the success of HIV-related programs. The purpose of this study was to evaluate the inventory levels of HIV RDT kits at specific healthcare facilities in Zambézia province, Mozambique. METHODS: Using facility-level pharmacy stock surveillance data from October 2015 through September 2016, we assessed the inventory levels of HIV RDTs at 75 health facilities in 8 districts within Zambézia province, Mozambique. Using programmatically established categories (good, sufficient, threatened, or stockout), defined in conjunction with the provincial health authorities, descriptive statistics were performed to determine inventory control of HIV RDTs at the district and health facility levels. Monthly proportions of adequate (good + sufficient) inventory were calculated for each district to identify inventory trends over the evaluation period. To assess whether the proportion of inadequate stocks differed between RDT, a mixed-effects logistic regression was conducted, with inadequate inventory status as the outcome of interest. RESULTS: When viewed as a whole, the inventory of each test kit was reported as being at adequate levels more than 89% of the time across the 75 facilities. However, disaggregated analysis revealed significant variability in the inventory levels of HIV RDTs at the district level. Specifically, the districts of Inhassunge, Namacurra, and Pebane reported inadequate inventory levels (threatened + stockout), of one or both test kits, for more than 10% of the study period. In addition, a disparity between inventory levels of each test kit was identified, with the odds of reporting inadequate inventory levels of the confirmatory test (Uni-Gold™) being approximately 1.8-fold greater than the initial test (Determine™) (odds ratio: 1.82, 95% CI: 1.40-2.38). CONCLUSION: As Test and Treat programs evolve, a significant emphasis should be placed on the "test" component of the strategy, beginning with assurances that health facilities have the adequate inventory of RDT necessary to meet the needs of their community. As national policy-makers rely predominantly on data from the upstream arm of the supply chain, it is unlikely the disparity between inventory levels of HIV RDTs identified at individual districts and specific health facilities would have been recognized. Moving forward, our findings point to a need for (1) renewed efforts reinforcing appropriate downstream forecasting of essential medicines and diagnostic tests in general and for Uni-Gold™ test kits specifically, and (2) simple metrics that may be routinely collected at all health facilities and which may then easily and quickly flow upstream so that policy-makers may optimally allocate resources.

RESUMO

Hazardous drinking places individuals at risk for adverse health events, resulting in a major public health burden globally. Patterns of alcohol consumption among women in Africa remain poorly understood. We aimed to describe alcohol consumption in a representative sample of female heads-of-household in Mozambique. A 2014 population-based cross-sectional study of 3892 heads-of-household was conducted in Zambézia Province. Data on alcohol use were collected using the Alcohol Use Disorders Identification Test (AUDIT). Sociodemographic characteristics were summarized by alcohol use. A multivariable proportional odds model adjusted for age, education, Portuguese fluency, marital status, income, social support, depression, food insecurity, currently pregnant, and child mortality was used for the ordinal AUDIT scale as outcomes with robust covariance to account for clustering of respondents. The overall prevalence of current alcohol consumption among female heads-of-household was 15%. The mean PHQ-8 score was 2.7 (SD 4.7). The prevalence of women considered "hazardous drinkers" (score >4) was 8%. In bivariate analyses, depression, marital status, currently being pregnant, food insecurity, and death of a child were associated with higher risk of hazardous drinking. After adjusting for multiple characteristics, depression (aOR: 2.20 [1.28, 3.76] p = 0.004), death of a child (aOR: 2.44 [1.46, 4.07] p = 0.001), and being currently pregnant (aOR: 1.83 [0.99, 3.39] p = 0.002) were associated with hazardous drinking behavior. Being single (aOR: 0.48 [0.29, 0.80], p = 0.017) and food insecure (aOR: 0.96 [0.92, 1.00], p = 0.050) showed a protective effect on hazardous drinking behavior. The percentage of female heads-of-household in north-central Mozambique that regularly drink alcohol was lower than expected. This may be due to the unique characteristics of female heads-of-household and the extreme poverty pervasive in Zambézia.
